cnosonn ron BOTTLES.

My invention relates more particularly to that class of closuresfor'bottles, jars, and other rigid containers in which the bottle neck,for example, is enlarged by a peripheral head or otherwise around themouth of the bottle, and the ca ,for example, that known as the Crowncap, which is provided with a cork or other lining in its crown to sealthe mouth of the bottle, is crim ed or compressed to form-a'contractedrim ound tightly around the neck of the-bottle, and secured againstdisplacement thereon by the enlargement around the mouth-of the bottle.The Crown cap has heretofore generally been removed when desired by aspecial tool for the, purpose which often distorts the cap in removal sothat it cannot be used again even for temporarily closing the container,as when only part of the contents is to be used at a time. The primaryobject of my invention is to provide a neck for bottles, jars, andsimilar containers so formed that the. cap, when 'crimped or compressedthereon, as by means of the ordinary crimping machines in com- '.monuse, will be securely held inplace against leakage and displacement andyet can'be' easily removed by hand without the use of an tool, and afterremoval can be easily rep aced on the neck for temporarily closing-thecontainer when onlypart of its contents have been used.

To this and other ends, my invention consists broadly of a container,for example, a bottle, having a neck formed with peripherally andupwardly inclined beads or shoulders to engage inward projections, orsome of the' corrugations, if a Crown cap, on the inside of the rimthereof and lift the cap off the neck as the cap is turned, and with up'ivardly and outwardly "inclined parts by whichthe'rim of the cap, whencrimped or contracted around the neck, is locked in place and which,when-the cap "is turned by hand, will act to expand the rim and ease theliftin of the cap off the neck.

y invention also consists more specifically, in forming the peripherallyand upwardly inclined shoulders on the'upper sides of. beads raised"around the neck of the bottle, the undersides of which when the severalbeadsoverlap, serve with the outwardly inclined" parts ofthe neck, toenga e the in ward cap projections and lock t ecap in place.

Application filed April 17, 1928. SerialNo. 270748.

The inclined shoulders on the neckmay also bev formed of inclinedgrooves in the neck.

The broad invention and the specific form thereof above briefly stated,'are not claimed herein but are described and claimed in a separateapplication for patent filed by me April 17th, 1928, Serial No. 270,750.

The present application is specifically for I another specific form ofmy broad invention described but not claimed in my said otherapplication, and consists in making the outer sides of the inclinedbeads instead of or together with the body of the neck between the same,inclined outwardly and upwardly, so that'the inclined parts of the neckformed by said outer sides of the beads will serve to lock the capinplace when crimped or contracted thereon and to spread the rim of thecap and e'ase its lifting and removal when turned and lifted by theupwardly and peripherally inclined shoulders formed by the upper sidesof the beads.

In order that my invention may be fully understood, I shall firstdescribe in detail the mode in which I at present prefer to carry thisinvention into practice, and then particularly point out the inventionin the claim. Reference is to be had to the accompanying drawingsforming part of this application in which like parts are designated bythe same numbers in all the figures.

Figure 1 is a sectional side view of a bottle neck with Crown capembodying my invention.

Figure 2 is a cross sectional view of the same on the line 2-2, Figure1.

Figure 3 is a side view of said bottle neck.

In the drawings, 19 designates the bottle neck and 18 the body thereofwhich may be cylindrical as shown or slightly inclined upwardly andoutwardly. Y

The bottle neck is formed with beads, the upper sides 21 of which areinclined up- 'wardly and peripherally-toward the mouth- 23 of :thebottle to form upwardly and peripherally inclined shoulders.

The outer sides 22 of the beads are inclined upwardly and outwardlytoward the mouth of the bottle to form upwardly and outwardly inclinedparts of the neck.

When the rim 24 of a Crown cap 25, for example, is crimped or contractedaround the neck 19 thus formed, the upwardly and 1 the internalprojections on the rim 24, en,

outwardly inclined arts 22, co-operate with the inward projectlonsformed by the corrugations on the inside of the rim 24, some of "whichenter the grooves between the beads to lock the cap securely on theneck.

When the cap is turned by hand some of gage and ride upward on theupwardly and peripherally inclined shoulders 21 of the beads and liftthe cap, which is slightly flexible, off the neck.

At the same time the upwardly and outwardly inclined parts 22 of thebeads on the neck act to spread the flexible rim 24 of the cap andfacilitate the removal of the cap from the neck.

As the cap, being flexible, is not unduly distorted by the lifting andspreading process, it, after removal, can be easily slipped over thecap-expanding and, securing parts 22 and replaced on the necktemporarily to cover the remaining contents of the bottle when only apart thereofhas been used. It is evident that this improved form ofcontainer neck may be used with other caps than Crown caps, which have arim adapted to be contracted below the mouth of the bottle and interiorprojections on the rim which will engage the upwardly and peripherallyinclined lifting shoulders on the neck.

It is also evident that other changes may be made in the practice of myinvention will engage the inward projections of a cap crimped orcontracted thereon and lift the cap off the neck when turned, and theoutwardly inclined parts will assist in locking the cap when contractedon the neck, and ease its lifting by the shoulders when it is turned.

In testimony whereof I afiix my signature.

ANTHONY F. MCDONNELL.
